Is it possible to restrict NeatImage to working on the blue channel only? I scan color negs with most noise in the blue channel and lots of detail in the R&G, but I can't figure out how to apply the noise reduction to blue only. The selection allows red only, I think, but I can't change it to blue.
Yes, you can switch the working color space from YCrCb to RGB (in the Device Noise Profile tab) and then adjust the filter settings in the Noise Filter Settings tab to filter only one channel.
I don't get that ability when using NI as a Photoshop plugin. Only the R channel is highlighted, G & B are grayed-out. It does work OK as a stand-alone.
